Answer:

Step-by-step explanation:
In order to get a product of 1, you must multiply
with another fraction that will result in the same value for the numerator and the denominator, which is its <u>reciprocal</u>.
In other words,
.
Therefore, you could multiply
by
to make a product of 1.
First you need to get x on one side of the equation and to do that subtract 2a from both sides.
28 + 2a = 5a + 7
-2a -2a
28=3a+7
Then we need to get a alone by subtracting 7 on both sides.
28=3a+7
-7 -7
21=3a
Finally divide each side by 3 and you should get a = 7. Hope this helps!
